The Cell Review
Osmosis is a form of ________transport.
• passive
List 2 ways in which plant and animal cells are structurally
different.
• Animals cell = many vacuoles, Centrioles and Lysosomes• Plant cell= large water vacuole,
chloroplast, cell wall
What part of a phospholipid would be touching water?
• Phosphate head
What type of cells are plant and animal cells?
• Eukaryotic Cells
Organelle: Site of chemical reactions; holds organelles
• cytoplasm
What type of eukaryotic cell is the following?
• Plant
The shape of the cell depends on its _______.
• function
Identify:
• Mitochondria
The movement of materials across the plasma membrane by the use of
transport proteins is called____________________.
• Facilitated diffusion
Organelle: Contains digestive enzymes that break down molecules
• Lysosomes
Suppose a ribosome attached to the rough ER made a protein. Where
will it go next?
• Golgi body
List one difference between eukaryotic and prokaryotic cells.
• Prokaryotic cells = no nucleus; no membrane bound organelles• Eukaryotic cells = nucleus; have
membrane bound organelles
The plasma membrane of the cell is specific in what is allowed to enter and
exit the cell. This is an example of_________________.
• Selectively permeable or • Semi-permeable
A function of chloroplasts would be ____________________.
• Photosynthesis
Identify:
• Water Vacuole
When food is pushed out of the paramecium, (one celled protist)
this process is called______.
• Exocytosis
What part of a phospholipid would be NOT be touching water?
• Fatty Acid Tails
This macromolecule is found among the phospholipids and helps prevent
the fatty acid tails from sticking together.
• Cholesterol
Identify:
• Nucleolus
Which scientist came up with the word “cell” based on the
cells where monks lived?
• Robert Hooke
The pressure that exists inside a plant cell when it swells is
_________ pressure
• turgor
What part of the phospholipid would be touching water?
• Phosphate head
What is the significance of all the folds in the mitochondria?
• The folds increase the surface area so this small organelle can make a lot of energy
What would be the NORMAL environment for a plant cell?
• Hypotonic
Organelle: Provides support for plant cells
• Cell Wall
Osmosis does not occur when a cell is placed into a(n) _______ solution
• isotonic
Why does active transport use cellular energy?
• Active transports moves molecules from an area of LOW to HIGH
concentration (against the concentration gradient)
Identify:
• Chloroplast
The first person to observe and describe microscopic organisms and
living cells was
• Anton Leeuenhoek
What type of active transport is used to remove wastes and mucus
from a cell?
• Exocytosis
How are the mitochondria and chloroplast similar?
• Both help make energy
• 1 = phosphate head• 2= lipid tails
